Hey everyone

Ok my one truck hasn't been on the road for a lil over 3 years now. It has 440 thousand miles on it. It's been sitting because the tranny went out for the second time in its life time. I put a new 4l60-E in it.

Well the truck at the time had a real bad multiple misfire with the flashing service engine soon light. So while I was doing the tranny I threw in a used set of the upgraded fuel injectors I got from a different truck that had a locked up engine. That remedied that issue.

I finally started the truck earlier on this year around September and it idled fine drove good had lotsa power and spunk. Had to put a new t-stat in and power steering pump and lines.

Ok my dad drove the truck up to my new house (4 hrs) north and said it's cutting in and bad and was tough to start. When he got in my driveway it killed. Checked the codes and crankshaft position sensor plus camshaft position sensor codes were both going off so I figured the timing must be off. So I put in a new timing chain and gears and crank sensor.

I didn't lower the pan in fear of having my gasket crack on it during that process no big deal but noticed I couldn't start my truck not even a pop when cranking. Ok crank sensor my new one wouldn't push in and it's negative 20 degrees up here so I decided to throw the old one in temporarily to see if that helps. Nope nothing. So I pulled that crank sensor back off and I got some super black RTV sealant on the relucter ring. Ok I pulled everything back apart.

Now before I pull the cover all the way back off should I lower the pan? If doing so what are the chances the old gasket will survive with 440 thousand miles and 20 years of Wisconsin and Minnesota roads?

I believe the gasket that's on there is 4 pieces.

What all do I have to remove if it does crack? The oil cooler and filter adapter, starter motor, exhaust crossover, front driveshaft, and something on the front diff?

What exactly do I remove on the front diff to give clearance?
Or could I remove the engine mount bolts and jack the engine up a few inches from the harmonic balancer to gain this?

As always thanks for any replies I really appreciate all the help everyone from this forum has given me. I really wanna get my truck back on the road.
